We have organized several common questions for our clients,may help you sincerely:

1.Q: Why would you choose ductile iron pipe rather than other pipe materials?

 A:The reasons are obvious for that not only ductile iron pipe possesses the inherent strength and flexibility of ductile iron, combined with proven corrosion protection systems, but also the cost savings can be achieved from design to installation and commissioning.

 2.Q:Why can you guarantee the inner of pipes can’t be corroded?

 A: High alumina cement mortar lining and sulphate-resistant cement mortar lining. These two special linings are applicable to inner anti-corrosion for sewage pipes, improving resistance to erosion of the sewage components.

Q:Are ductile iron pipes available for cutting and are there any relevant specifications?
Can be cut, the specification is based on the original specification, just for some engineering needs
Q:What are the risks in the process of conveying ductile iron pipes?
Lifting: be careful lifting pipe, don't let the pipe shaking, lifting pipe by wire rope, sling and special sling, wire rope no single, for the protection of pipe coating, rubber or similar materials can be used to wrap up the rope. The use of hook, for the protection of the cement lining layer is not damaged, will hook with rubber or similar material wrapped up, especially in the hoisting of large diameter pipe, will not be fixed in the socket with hook in end strip or pipes.
Q:What effect does magnesium play in nodular cast iron?
Magnesium can be graphite precipitated in spherical form.But the specific mechanism is not clear, and now it is still debated in the academic circles.In addition, magnesium and sulfur generate MgS, which removes S from molten iron, which impedes the formation of spheroidal graphite.Therefore, Mg has two functions to eliminate the influence of S on Nodular Iron and promote the precipitation of graphite in spherical form.
Q:Advantages and disadvantages of ductile iron pipes
Comparison between ductile iron pipe and universal cast iron pipe: the process of making ductile iron pipe is cast by adding alkaline earth metal or rare metal such as magnesium and calcium in the raw material of common cast iron pipe. The casting process of nodular cast iron pipe casting method and water cooled centrifugal casting hot continuous casting method, which method is water, the world's most advanced technology, different technology of ductile cast iron and cast iron pipe technology performance comparison, not only to maintain the ordinary cast iron pipe corrosion resistance, and has the advantages of high strength and toughness good, thin wall, light weight, impact resistance, bending performance, convenient installation.
Q:What do ductile iron pipes need to connect with three? Can I contact it directly?
The new process adopted at present is groove connection. With groove parts, of course, your ductile iron tube should also be grooved!
Q:Does the cast iron have size 250? What's the performance?
You should be the casting grade or material, if it is ductile iron, said generally between QT400-15 or QT700-2 different indicators, said in front of the tensile strength, the elongation rate refers to the back, China is now the lowest grade of nodular cast iron material is QT400-15, such as QT250.In addition, the number 250 you refer to may also be a code name for ductile iron parts, such as 200, 300, etc., which are manufactured by the factory as required by the project.Gray iron, which has a 250 brand, is generally referred to as HT250, but it is not ductile iron.The machine on the ductile iron and gray iron are used, but generally not made of grey cast iron gear
Q:What is the difference between spheroidal graphite cast iron QT400-15 and QT400-15A? What does the A mean later?
This should be said in front of the material, and later add A, should refer to the grade
Q:Ductile iron pipe, socket connection, pipe length, you can cut open it?
Yes, but the pipe that needs cutting is a cut off pipe with a scissors mark.
Q:What are the requirements for the hydrostatic test of ductile iron pipes?
The hydraulic pressure test shall be carried out in the backfill before trying to allow the pressure after passing the backfill, backfill, the graded gravel fill to 300mm above the top of pipe, and then the soil backfill, backfill process by 200~300 tamped pipeline above 500mm within more than 500 can be used in artificial ramming, mechanical compaction. The degree of compaction shall not be less than 0.93.
Q:Ways of connecting ductile iron pipes
In our country, the national standards stipulated annealing, centrifugal casting, water delivery with ductile iron, straight pipe, pipe fittings, aprons and other technical requirements, China's production of ductile iron pipe products must meet the current national standards.
